whats the GCF of 15 and 35 and 70


Sagot :

Just think what do all the numbers have in common? What number can relate to all of them and is the largest number? That's how you find GCF, straight of the bat I can see that the GCF is 5 because nothing higher than five can match up to all of them, in other words nothing other than 5 or higher than 5 is a factor of all the numbers.
